Fungal infections of the skin are given the general name ‘tinea.’ Superficial fungal infections affect the top layers of the skin including the mucous membrane, hair and nails. Common examples of superficial fungal infections are athlete’s foot, jock itch, ringworm and candida. Deep fungal infections are of much more concern as they can spread to the blood and internal organs if left untreated. Yeast and fungal infections are typically treated with topical or oral antifungal medications. Antibiotics may lead to fungal infections despite killing bacteria. Fungus tend to grow in warm, moist areas of the body such as the armpit, groin region and feet.
